Throttle response is much better, shifts the way it should and now my speedometer matches my tire size.

Got this to help improve gas mileage for a F250. So far I still get the same gas millage as before I install it. I have driven about 300 miles wit no change. Pulling camper this weekend hopefully it help with this. If not it was a waste on money
